Lockout/Tagout (LOTO) Program<-Program Name
29 CFR 19.10.147
Revised Date: 8/10/23
Author: Dean Manley
Purpose
Lockout/tagout (LO/TO) programs are designed to prevent the accidental activation or expelling of energy from equipment during servicing or maintenance tasks. The procedures listed herein must be used to ensure safe operation on and around equipment where one of the following hazards exists: electrical, mechanical, hydraulic, chemical, pneumatic, or thermal. When followed correctly, utilizing proper LO/TO techniques will ensure all affected personnel avoid the risk of unexpected start-up or energization of the equipment being serviced. Hence, avoiding the potential for serious injury or fatality.
Scope
The Occupational Safety and Health Administration (OSHA) requires employers to implement guidelines to control employee exposure to hazardous energy during the maintenance and servicing of machines and equipment in accordance with 29 CFR 1910.147. This policy covers the procedures to be followed while working on or near equipment where the unexpected release of energy could cause physical or bodily harm to workers. Examples of such equipment include but is not limited to; light fixtures, boilers, pumps, elevators, fan systems, starters, disconnects, breakers, compressors, HVAC units, steam line valves, and automobiles. This policy applies to all St. Lawrence University (SLU) employees and all professional contractors conducting business at SLU.
Definitions
Affected User/Employee: A person whose job requires them to operate or use a piece of equipment on which servicing or maintenance is being performed under LO/TO, or whose job requires them to work in an area where such servicing or maintenance is being performed.
Authorized Employee/User: A person who locks out or tags out machines or equipment to perform service or maintenance on that particular item. An affected employee/user becomes an authorized employee/user when that employee’s duties include performing service or maintenance on machines or equipment covered under this policy.
Capable of Being Locked Out: An energy-isolating device is capable of being locked out if it has a hasp or other means of attachment to which a lock can be affixed, or it has a locking mechanism built into it. Note: Other energy isolating devices are capable of being locked out, if lockout can be achieved without the need to dismantle, rebuild, or replace the energy isolating device or permanently alter its energy control capability.
Energized: Connected to an energy source or containing residual or stored energy.
Energy Source: Any source of electrical, mechanical, pneumatic, hydraulic, chemical, or thermal energy that poses a hazard to employees.
Energy Isolating Device: A mechanical device that physically prevents the transmission or release of energy, including but not limited to the following: a manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy. Push buttons, selector switches and other control circuit type devices are not energy isolating devices.
Hot Tap: A procedure used in the maintenance or repair of equipment which involves welding under pressure in order to install connections or appurtenances.
Lockout: The placement of a lockout device on energy isolating equipment in accordance with an established procedure ensuring that the energy isolating device and equipment being controlled cannot be operated until the lockout device is removed.
Lockout Device: A device that uses a lock, either key or combination type, to hold an energy isolating device in a safe position and prevent the energizing of a machine or other equipment. Included are blank flanges and bolted slip blinds.
Normal Operations: The utilization of a machine or other equipment to perform its intended function.
Servicing/Maintenance: Workplace activities such as constructing, installation, setting up, adjusting, inspecting, modifying, maintaining, lubricating, cleaning, or making other adjustments on energized equipment.
Tag Out: The placement of a tag out device on an energy-isolating device, according to established procedure, to indicate that the energy isolating device and the equipment being controlled may not be operated until the tag out device is removed.
Tag Out Device: A prominent warning device, such as a tag and a means of attachment, which can be securely fastened to an energy isolating device according to an established procedure, to indicate that the energy isolating device and the equipment being controlled may not be operated until the tag out device is removed.
General Provisions
The following situations are not subject to the procedures outlined in this document:
- Work on plug and cord type electrical equipment, for which exposure to the hazards of unexpected energizing, startup, or the release of stored energy of the equipment is effectively controlled by the unplugging of equipment from the energy sources and by the plug being under the exclusive control of the employee/user performing the servicing or maintenance.
- Hot tap operations involving transmission and distribution systems for substances such as gas, steam, water, or petroleum products when they are performed on pressurized pipelines, provided that it is clear that continuity of service is essential, shutdown of the system is impractical and documented procedures and special equipment are implemented which will provide proven and effective protection for employees and users.
- Note: There are no SLU employees authorized to perform hot tap operations. If hot tap is required, work must be contracted out to an authorized outfit.
- Service or maintenance that takes place during normal production operations, such as lubricating, cleaning and making minor adjustments and simple tool changes. Except, when an employee/user is required to place any part of his/her body into an area on a machine or piece of equipment.
- Note: Each department is responsible for understanding appropriate LO/TO procedures relevant to their specialized equipment.

Sequence of LO/TO Procedures
St. Lawrence University will provide the necessary equipment to effectively lockout or tagout energy isolating devices. Lockout/tagout equipment will be the only devices used for controlling energy and shall not be used for other purposes. Any devices used for LO/TO will be capable of withstanding the environment to which they are exposed for the maximum period they are expected to be exposed. The devices will be substantial enough to prevent removal without excessive force. LO/TO devices will indicate the identity of the employee who applied the device, and the tagout device will warn against the hazard if the equipment is energized.
Note: If deenergizing is chosen, a thorough inspection should be performed to identify all potential sources of hazardous energy, including adjacent equipment. Energy is considered adequately isolated, blocked, or dissipated when an unplanned event would not reactivate the flow of energy.
The person(s) performing LO/TO work shall:
- Determine the need to control hazardous energy by method of lockout/tagout.
- Notify all affected employees that a lockout or tag out system is going to be utilized. Explain why and how LO/TO is being utilized to all affected users.
- Ensure the machine or equipment is clear of all tools, materials, and personnel.
- Know and understand all potential hazards, magnitude of energy, and the means of controlling energy prior to shutting down equipment.
- Shut down machine or equipment via normal stopping procedure.
- Operate the switch, valve, or other energy isolating device to ensure the equipment is disconnected from the energy source(s). Ensure all stored energy (such as that in springs, elevated machine members, rotating fly wheels, hydraulic systems, air, gas, steam or water pressure) has been alleviated or is restrained by proper blocking or bleeding down practices.
- Attach the lockout device(s) to ensure the energy isolating mechanism is in the “safe or “off” position.
- Review normal operating controls and owner’s manual to verify all potential sources of energy have been disconnected.
- Note: When possible, you must place the tags at the same point at which a lockout would have been attached. If this is not feasible, locate the tag as closely as safety allows to the device in a position that will be immediately obvious to anyone who attempts to operate the device.
- Report all locked-out equipment to the shift supervisor at time of lock out, and again once work has been completed and power is restored.
- Inform all rotating shift workers of LO/TO equipment and scope of work, if applicable.
Requirement for LO/TO Devices
All devices must meet industry standards for the intended use of the device. Each lockout and tag out device must indicate the identity of the authorized employee using the device and must warn against re-energizing of the equipment. Questions regarding standardization and procurement of LOTO equipment can be directed to the relevant department supervisor or EHS. EHS must review and approve all LO/TO equipment prior to purchase.
The energy isolating devices must be locked out/tagged out with assigned locks and tags. The LO/TO device must be readily identifiable and must not be used for any purpose other than energy control. While conducting LO/TO operations, the following conditions must also be met:
- Locks must be individually keyed.
- One key must remain in the possession of the authorized employee/user, and the other must be placed in a secure location in the appropriate supervisor’s office.
- Supervisors shall maintain an accurate and current list of key assignments with proper sign in/sign out documentation.
- The name of the authorized employee and the date shall be legible on each tag at time of use.
- Note: Tags may evoke a false sense of security. Tags are essentially warning devices affixed to energy isolating devices and do not provide the physical restraint that a lock would provide.
Restoring Machines or Equipment to Normal Operations
These procedures shall be followed when restoring machines or equipment back to normal operation:
- After servicing/maintenance is complete, re-install all relevant parts and subassemblies. Re-install all guards and protective devices.
- Remove all blocks or other restraints from the operating area of the equipment.
- Remove all tools and maintenance materials from the operating area.
- Ensure all personnel are safely positioned clear of the operating area and verify equipment is ready for operation.
- Remove energy isolation device (authorized employee only) and re-connect all relevant breakers, valves, and pipe fittings.
- Re-energize equipment.
- Note: The removal of some forms of blocking may require reenergization of the machine/equipment before safe removal.
Emergency Removal of a LO/TO Device
Only the employee who installs a lockout or tagout device shall remove it. However, in the extreme circumstance where such employee is not available, the device may be removed with the permission and direct supervision of the relevant department manager provided that the following is verified:
- The authorized employee who installed the device is not at the facility.
- All reasonable efforts are made to contract the employee regarding the need to remove the LO/TO device.
- The employee is informed of such removal before they return to work at the facility.
Group Lockout/Tagout
Group LO/TO services shall be used whenever maintenance or servicing of energy isolated equipment is performed by a crew, department, shop, or group of greater than one person. Depending on the circumstances of how the group, crew, shop, or department is arranged, the authorized, appointed person shall exercise one of the following two procedures.
- If more than one authorized individual must perform maintenance on a machine or piece of energized equipment, then each employee performing work shall place a lock/tag on the energy isolating device.
- If one designated individual leader of a work crew (foreman, supervisor, shop manager, etc.) deems it as best practice, then that person may lock or tag out the equipment for the entire group. Note: If this method is chosen, it shall be the responsibility of the individual who initiated the LO/TO procedure to carry out all necessary steps of this protocol while most importantly communicating with his/her team members throughout the LO/TO process.
Work on Live/Energized Circuits or Equipment
Any work conducted on live or energized parts shall only be issued to properly trained and authorized employees. In the event that work must be performed on live/energized circuits or equipment greater than 50 volts for reasons such as troubleshooting, or working on circuits that form an integral part of a continual industrial process, the following criteria must be met:
- Ensure all proper PPE is available and worn prior to operating.
- Ensure there are at least two employees involved on the worksite of live equipment.
- Ensure completion/review of Energized Electrical Work Permit (appendix D).
Note: Live parts that operate on 50 volts (to ground) or less do not need to be de-energized if there are no increased exposures to electric burns or arcs.
Vehicle LO/TO
Authorized employees who are subject to potential exposure to accidental start-up of automotive vehicles or equipment are required to lock and tag the equipment throughout the duration of vehicle service. Affected employees who utilize the equipment being serviced for their scope of work shall not remove a lock or tag under any circumstance. Unauthorized removal of a lock/tag or utilization of equipment with a lock/tag in place may result in disciplinary action.
Training
The Department of Environmental Health and Safety must provide training to all authorized employees/users to ensure that the purpose and function of the energy control procedures are understood. It is the employer’s responsibility to provide employees with the knowledge and skills necessary for the safe application, usage and removal of the energy controls that are required. Training sessions must be scheduled on a periodic basis for any new personnel who may require hazardous energy control training, or when the job assignment or workspace/equipment of a given task is altered. Additional training responsibilities include:
- Each supervisor must forward a list of authorized employees that are to receive hazardous energy control training to the EHS department.
- Both EHS and department supervisors are to ensure that periodic refresher training is completed by affected employees.
- Employees shall be re-trained whenever there is a change in energy control procedures.
- The employer shall maintain current and accurate LO/TO training records with names and dates of employees trained.
- Training shall be in accordance with OSHA Lockout/Tagout standard 29 CFR 1910.147(c)(7).
There will be three specific types of training offered to SLU employees:
- General Awareness: All employees who may be affected by a LO/TO shall be trained to an awareness level of this procedure. This training will teach affected employees to recognize LO/TO devices if encountered in their work area. Employees who complete this training will know their basic role in LO/TO procedures. This training will be provided by EHS or Human Resources upon employee orientation.
- Authorized Employee Training: Any employee who is authorized to perform LO/TO as part of their work scope is required to take this training. This training will ensure the employee possesses the skills and knowledge to fully implement this general procedure. This training will be provided by the applicable department head or supervisor.
- Machine/Equipment Specific Training: Supervisors and shop managers are required to train affected employees on each piece of equipment or machinery that may require the need for LO/TO under their scope. This training shall include any site-specific procedures relevant to the equipment at hand. This training should be recorded and maintained by the shop supervisor.
Enforcement
The department of Environmental Health and Safety along with facilities and shop managers should conduct periodic inspections to ensure that the energy control procedures and requirements are being followed. The facilities or shop manager must correct any inadequacies and/or deviations from the procedure noted during period inspection. Any unauthorized removal of lockout/tagout equipment, or unauthorized use of equipment that is locked out or tagged out may result in disciplinary actions.
